SuperMax 19-38 vs Powermatic PM2244: Width and Setup
Choose Powermatic PM2244 when the move from nineteen to twenty-two inches in one pass, or from thirty-eight to forty-four inches in two, addresses recurring work. Choose SuperMax 19-38 when its documented envelope is sufficient and its installation requirements suit the shop. The decisive difference may be the dust system rather than the extra width. This source-based comparison does not claim measured finish, accuracy, or reliability results.

Three inches matter when your panels use them
Measure the assemblies you regularly sand, including rough-width allowance. Through nineteen inches, both machines fit the width requirement. Above nineteen through twenty-two inches, PM2244 can keep a panel within its single-pass capacity while the SuperMax requires its documented wide-panel procedure. That is a concrete handling distinction, not a guaranteed production-time saving.
For over-width work, SuperMax documents thirty-eight inches in two passes and Powermatic forty-four. If your planned assembly is forty inches wide, only Powermatic covers that width among these two. If nearly all work is comfortably under nineteen, select based on the complete station and operating routine instead of maximum capacity alone.
Thickness matches, but minimum length differs
Both manuals specify thickness from 1/32 to four inches. SuperMax lists a 2-1/4-inch minimum length; Powermatic lists 2-3/8 inches. That difference is small in absolute terms but can matter for a specific short blank. Check every stock rule and the suitability of the piece rather than treating minimum length as the only condition.
Thin-stock ratings likewise do not establish permission for every veneer or carrier technique. Read the actual feeding and support requirements. If your project relies on an exceptional workpiece shape, obtain manufacturer guidance before buying a machine around it. A slightly smaller published minimum does not make an otherwise unsuitable piece safe.
Dust collection can change the whole purchase
SuperMax’s cited manual calls for at least 600 CFM recommended collector capacity through a four-inch port. Powermatic specifies 800 CFM minimum extraction with a four-inch port. The identical connection size does not make those requirements interchangeable. Include any necessary collection change when assessing the PM2244 installation.
SuperMax specifies 110V single-phase 20A service and expressly prohibits rewiring the cited 19-38 for 220V. Powermatic specifies 115V only with a recommended 20A circuit. Follow each machine’s electrical instructions rather than assuming a voltage conversion is an upgrade option. Resolve supply suitability before arranging delivery.

SuperMax describes feed-load control and a wide-panel adjustment lever. Powermatic’s control panel and height indication are useful demonstration topics. Ask how each operator establishes a starting reference, recognizes a feed-load response, and returns the machine to normal setup after wider work.
A display does not independently measure the finished board, and an overlap adjustment does not eliminate verification. Bring a representative permitted sample to a demonstration if available and inspect thickness at several points. Ask for an explanation of the settings used. This tests whether the workflow is understandable without pretending a single demonstration establishes long-term performance.
Compare the complete station and ownership process
Get written package details for tables, stand, mobility equipment, and initial abrasives. Identify where a long or broad assembly will rest on both sides and how you will bring it back to the infeed. A nominal machine footprint cannot capture that handling route. Also reserve access for safe abrasive changes and dust-connection maintenance.
Request the replacement wrap and conveyor identifiers, current service contacts, and delivery-damage procedure. Include those items, extraction equipment, and installation assistance in an itemized quote. No current price advantage is claimed. The better purchase is the complete configuration that meets your needs, rather than a bare machine total compared with a fully equipped competitor.
Final choice: let width and extraction decide first
PM2244 is the clearer capacity match for repeated twenty-to-twenty-two-inch single-pass panels or over-width assemblies beyond thirty-eight through forty-four inches. Make that choice with its 800 CFM requirement accounted for, and judge the control arrangement on an explained demonstration rather than on appearance alone.
SuperMax 19-38 is a sound candidate when nineteen-inch single-pass and thirty-eight-inch two-pass work cover the plan and its complete installation fits better. This comparison covers the drum-sanding 19-38, not the brush or combination machine. If both fit, compare support access, included equipment, and the operating routine you can repeat confidently; the published information does not establish a universal finish-quality winner.
Questions, answered
Does Powermatic take thicker stock?
No. Both cited models specify the same 1/32-to-four-inch thickness range. Powermatic’s documented advantage here is width.
Can I reuse a collector selected only for 600 CFM?
Do not assume it meets PM2244 requirements. Powermatic specifies 800 CFM minimum extraction, so assess the actual proposed system against that requirement.
Which handles forty-inch panels within its rating?
PM2244 documents forty-four-inch two-pass capacity. SuperMax 19-38 documents thirty-eight inches in two passes.
